Title: Crankpin rolling apparatus
Inventor: HAYASHI TAKEHIKO
IPC: B24B39/04
Filed: 1983-08-04
Abstract: A crankpin rolling apparatus is provided wherein plural pairs of upper and lower arms 31,32 are pivotably carried by respective hinge pins 30 extending in parallel relation with the rotational axis of a workpiece support device. A pair of upper and lower roller holders 34,35 each rotatably carrying burnishing rollers are respectively mounted on each pair of the upper and lower arms. When the plural pairs of upper and lower arms are closed by respective pressuring actuators 38, the pair of upper and lower roller holders arrest a corresponding one of crankpins P1 of a crankshaft on the workpiece support means and pressure the burnishing rollers upon fillets formed on the corresponding one of crankpins. The hinge pins are respectively carried by a plurality of rocking members 23, which are independently pivotable about a support shaft 21 held by a machine frame in parallel relation with the rotational axis of workpiece support device. The crankshaft is rotated and pivot movements of the rocking members 23 permit the rollers to follow a corresponding one of the crankpins. The positions of the arms 31,32 are adjustable to suit the crankshaft. <IMAGE>

Title: Thermal cracking of heavy hydrocarbon oils
Inventor: GOMI SHIMPEI
IPC: C10G51/02
Filed: 1984-02-27
Abstract: A heavy hydrocarbon feed stock is, after being heat-treated in a first cracking zone 2, introduced into a second thermal cracking zone 20 for obtaining a thermally cracked product and a pitch product. The second cracking zone has a plurality of cracking reactors 3, 4, 5 which are connected in series, through which is successively passed the treated feed stock and to each of which is supplied a gaseous heat transfer medium to maintain the liquid phase therein at a temperature sufficient for effecting the thermal cracking and to strip the resulting distillable, cracked components from the liquid phase. The thermal cracking temperature in each reactor is so controlled as to become higher than that in its adjacent upstream-side reactor. The distillable, cracked components in respective reactors are removed overhead therefrom and separated at 8 into a heavy fraction and a light fraction, while the liquid phase in the downstream-end reactor 5 is discharged therefrom for recovery as the pitch product. The light fraction is recovered as a light product oil. The heavy fraction is fed to a third thermal cracking zone 30 for obtaining a tar-containing product which is recycled to at least one of the reactors 3, 4, 5 of the second thermal cracking zone 20. <IMAGE>

Patent GB-2187552-A (GB)
Title: Apparatus for monitoring movement of a fluid
Inventor: HARRISON PAUL MARK
IPC: G01P5/24
Filed: 1986-03-05
Abstract: In apparatus for monitoring movement of a fluid two circular plates 1 and 2 are arranged parallel to one another such that a fluid to be monitored passes between them. Five transducers are located in one of the plates 1, a central transducer 6 acting as a generating transducer and four circumferential transducers 7, 8, 9 and 10 acting as receiving transducers. During operation of the device, a tone burst is generated by the transducer 6 and energy is radiated into the fluid in a non-normal direction to the plate 1 to be received by the receiving transducers after reflection from the plate 2. By comparing the phase difference between pairs of receiving transducers the velocity and direction of the fluid may be determined. <IMAGE>

Title: Improvements in or relating to a belt conveyor
Inventor: BRIGGS AUBREY CHARLES
IPC: B65G17/42
Filed: 1986-03-12
Abstract: An endless conveyor belt 7, with buckets or other digging or scraping elements secured to its outer surface at spaced locations, has at least one row of discrete blocks of resilient material bolted to the inner surface of the belt to form a continuous resilient material bolted to the inner surface of the belt to form a continuous resilient guide 7 member 11. As the endless belt passes around the end pulleys a wedging action is created as the discrete blocks, which have tapered side walls, press down into peripheral grooves 29 in the end pulleys which also have tapered, side walls but slightly narrower width than the members 11. The belt is preferably reinforced with embedded wire cables or fabric cords 9 so as to resist radial digging forces which tend to stretch the belt and pull it away from the end pulleys. Lateral forces generated as the digger is advanced into a pile of bulk material on a bias, which tend to cause the belt to creep laterally on the pulleys, are resisted by the restraint of the resilient guide members. Seals prevent bulk material from getting between the endless belt or its resilient guide members and the end pulleys, and scrapers remove any such material which gets past the seals and deflects it laterally out of the belt loop. <IMAGE>
